Sequelae of other and unspecified infectious and parasitic diseases (B94)
The ICD-10 code B94 covers the sequelae, or long-term complications, following various infectious and parasitic diseases. These codes are used to document the aftereffects experienced once the initial infection has resolved but has left residual health issues.
Specifically, B94.0 identifies sequelae of trachoma, which may be noted as lasting conditions following infection by Chlamydia. For viral infections, B94.1 and B94.2 capture sequelae of viral encephalitis and viral hepatitis, respectively, also referred to as late effects of these diseases. The code B94.8 is a broader category used for sequelae of other specified infectious and parasitic diseases, including diverse conditions such as postherpetic scars, arthritis following infections, or post-infectious glomerulonephritis. Lastly, B94.9 includes sequelae from unspecified infectious or parasitic diseases, used when the precise infection is unknown but ongoing complications persist, like postinfectious neuralgia or post-viral depression. These codes help medical coders accurately report the continuing health impact related to prior infections for proper patient management and insurance purposes.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Gingival Recession
Exposure of the root surface when the edge of the gum (GINGIVA) moves apically away from the crown of the tooth. This is common with advancing age, vigorous tooth brushing, diseases, or tissue loss of the gingiva, the PERIODONTAL LIGAMENT and the supporting bone (ALVEOLAR PROCESS).
